one - three one - three one -

It's 9/8 time, which is counted as if in waltz time - 'One and a two and a three and a'

It's 'compound time' in that the three beats are each subdivided into three, which in turn are subdivided into two.

The beat is a dotted quarter note, the sub beats are eighth notes (three to a dotted quarter) and the next subdivision is a sixteenth (two to an eighth)...
